CentOS 7 安装canvas编译失败

发布于 2021-01-26  1673 次阅读


很好,今天我们的主题又是canvas。真是自古原生包事儿多。

不过讲句公道话(?),其实很多问题是包作者或者(特指)node-gyp作者们没有考量到或不好考量到的问题。因此需要每位developer自己好好debug。

各位以后成功解决了什么bug的话也可以像这样发出来,并且确保搜索引擎可以正确收录。It saves peoples life.

那么按照惯例,先从日志文件开始:

npm install canvas执行到node-gyp rebuild这一步时,报错输出:(点此跳过日志)

从输出解读,error基本都是node自带的头文件有格式相关的错误。

那么,node的作者们可能会犯这种错误吗?显然不可能,格式错误他们自己都编译不过去。

所以先去node的官方仓库查看相关文件,对比一下源文件,看看是不是下载过程出现了错误(其实可能性不大)

检查没有问题,两边是一样一样的。

那么就只有可能是编译器的错误了。毕竟Uglify.js在读ES6+的JS时也是一个样子疯狂报格式错误。

于是我检查了node-gyp的版本,重装确认它是最新的。(这也是百度上对于node-gyp出错的最常见解决方案)

这里我犯了一个错误,就是以为编译器是node-gyp自带的。这就是我对Linux了解不深的问题了。然而node-gyp只是个包工头(自动建构系统),具体的活有更下边的人(编译器)干。

然后我检查了下cmake,在我的印象中C语言编译应该也要用到它,其实也是错误的。cmake也只是一个建构系统,并不是编译器。(所以说没有写过C的孩子根本不懂人间疾苦)

那么具体的编译器是谁呢?答案就是GCC。幸好Mac编程和看golang的时候有见过它的大名。于是键入:gcc --version

在我看到输出的文本里有句Copyright@2015的时候我已经感觉有点不对劲了,赶紧查一下gcc最新版的版本号。

我的天啊都到gcc 8了,怎么我的还是4,怪不得编译不了。

于是赶紧百度一下怎么在CentOS上升级gcc,文章开头的第一句话是:(顺带这老哥的页面标题挺可爱的)

Centos 7默认gcc版本为4.8,有时需要更高版本的,

我人傻了,立刻按照步骤更新。然后就成啦!

所以,回到之前说的,“很多bug可能只是包的作者们没想到而已”,这个问题就是典型的node-gyp在编译前没有检查编译器版本与代码的最低应用编译器版本的问题。但是,并不能什么事都靠包作者,特别是这种弱智问题只有在云服务器上的CentOS才会出现。真的想咨询一下各位,你们开发会用CentOS吗?

知道为什么学校要教C了吗?你不学可能连npm一个包都装不上。
